【摘要】：能源资源与负荷中心呈逆向分布是我国的能源产业布局的主要特征,为优化中国能源互联网建设,要坚持以电力建设为中心。随着经济的发展,电力行业对能源的需求呈现持续增长的趋势,但资源分布与电力需求侧分布不一致,因此,必须建立大容量、远距离的能源输送通道,确保中东部地区负荷中心的电力供给。本文以后评价理论和输变电工程建设内容为基础,通过对供电公司建设输变电工程项目后评价进行研究,为我国今后大规模建设的输变电工程积累后评价经验,研究适用电力行业工程项目建设的后评价方法和指标评价体系,从而对输变电工程的建设管理进行优化和改善。本文针对500kV输变电工程建设过程进行了详细的分析,从项目前期评价、项目施工评价、项目财务评价和项目可持续性评价四个方面着手构建500kV输变电工程后评价指标体系,确保各指存在的合理性并阐述其计算过程,根据指标衡量的重要程度及侧重点的不同应用熵权法确定权重,按照指标的相互关系运用模糊综合评价的方法建立500kV输变电工程项目后评价指标体系模型。实证研究以某500kV输变电工程建设项目为案例,结合工程实际竣工投产情况和各指标含义构建评价体系,根据工程实际管控过程对构建模型的准确性进行反向验证。本文构建了普遍适用的500kV输变电工程后评价指标体系和评价模型,为类似电网建设工程后评价提供了参考。
[Abstract]:The reverse distribution of energy resources and load centers is the main feature of China's energy industry layout. In order to optimize China's energy Internet construction, it is necessary to adhere to the power construction as the center. It is necessary to establish large-capacity and long-distance energy transmission channels to ensure the power supply of load centers in central and Eastern China. Based on the theory of post-evaluation and the construction content of power transmission and transformation projects, this paper studies the post-evaluation of power supply companies'construction of power transmission and transformation projects, and accumulates post-evaluation for large-scale construction of power transmission and transformation projects in China. In this paper, the construction process of 500 kV transmission and transformation project is analyzed in detail, from the pre-project evaluation, project construction evaluation, project financial evaluation and project sustainability evaluation. The evaluation index system of 500 kV power transmission and transformation project is constructed from four aspects of price, which ensures the rationality of each index and expounds its calculation process. The weight is determined by entropy weight method according to the importance of the index and the different emphases, and the 500 kV power transmission and transformation project is established by fuzzy comprehensive evaluation method according to the relationship between the indexes. The empirical study takes a 500kV power transmission and transformation project as an example, builds an evaluation system combining with the actual completion and commissioning of the project and the meaning of each index, and verifies the accuracy of the model according to the actual project management and control process. The standard system and evaluation model provide reference for similar post evaluation of power grid construction projects.
